Rainwater Collection Tank | Bidragon Steel Silos

A rainwater collection tank from Bidragon, also called a round water tank, is a circular corrugated sectional steel water tank with fewer metal parts, a lower price and easier installation, described as widely used around the world. The product documentation states that it is made of galvanized steel plates of different sizes as wall panels and food-grade waterproof cloth as the inner lining in contact with water, that any size can be customised, and that it is suitable for drinking water storage.

The documented applications include irrigation and domestic water uses such as greenhouse irrigation, greenhouse rainwater collection and temporary water storage at construction sites, and the documented service life is more than 10 years. The monthly production figures in the size table are production figures from the product page and must not be read as stock levels or delivery promises.

Specifications

Values in this table come from the product documentation for this product only. Where a value is not listed, it is marked as to be confirmed in inquiry, and it must not be taken from another product on this site.

Applications

Rainwater collection tanks serve irrigation, greenhouse, construction site and domestic water storage. The size table on this page applies only to this product and must not be applied to the galvanized water storage tank, which has its own product page and no size table. Monthly production figures are production figures, not stock or delivery commitments, and delivery scope is confirmed per project.

How this product fits in a storage line

Silo equipment is normally planned together with the silos it serves. A dust collector must match the dust point, the air volume and the cleaning regime, and a forming machine must match the container sizes and coil it will form. A buyer comparing silo equipment should therefore state the duty, the material and the existing handling line in the inquiry, rather than relying on a generic equipment figure.

What to confirm in your inquiry

Because silo requirements depend on the material, the site and the handling system, the following items are confirmed per project before any quotation is issued. Sending these details with your inquiry helps the supplier respond with a workable proposal rather than a generic price.

• Material to be stored, including bulk density, moisture content and flow behaviour, and whether the material is free-flowing or prone to bridging.
• Required storage capacity and any future expansion allowance, together with the available footprint and height limit at the site.
• Discharge method and downstream equipment, such as a screw conveyor, a pneumatic conveying line or a packing machine.
• Roof and bottom configuration, including whether a flat bottom, hopper bottom or elevated arrangement suits the discharge and foundation plan.
• Ventilation, level measurement, temperature monitoring and dust control requirements, where the stored material or local rules call for them.
• Surface protection and coating requirements, the installation method available at the site, and the delivery scope expected from the supplier.
• Any applicable design standard or local code that the project must follow, so that the proposal can be checked against it.

Where a value is not listed on this page, it is not a standard figure for this product. It is a project-specific figure to be confirmed in writing during the inquiry process, and it should not be assumed from another product on this site.
